WASHINGTON (AP) — A Republican congressman is telling a commission overseeing the controversial design for an Eisenhower Memorial to get moving on the long-stalled project before federal money dries up.

Republican Rep. Darrell Issa of California said that “the time for endless debate has to be over.” He told the National Capital Planning Commission that if the project continues to be delayed, it will become difficult to get more money from Congress to fund the memorial.

In an unusual appearance before the commission, Issa recommended that the group present design updates every two months.

Republican Rep. Aaron Schock of Illinois also made an unusual appearance before the commission to criticize the design. He said the imagery doesn’t covey the “majesty” of Ike and called it “a four-acre theme park without a coherent theme.”
